| Abstract: |
| Agricultural environmental damage cases are diverse and usually exhibit unique characteristics. Cases of artificial barrier layers in cultivated land are often complicated and uncertain, and the existing identification technology is costly, time-consuming, and limited by certain technical constraints, which greatly affects the timeliness and scientificity of judicial expertise. To evaluate the effectiveness of the high-density resistivity method in the identification of cultivated land destruction, nine measuring lines with a total length of 1 338 m and 682 effective electrodes were laid in a case site in Tianjin. The distribution characteristics of underground solid waste were investigated, and the results of the high-density resistivity method were validated by drilling exploration. The underground landfill solid waste depth ranged from 2.8 m to 7.0 m, and the distribution area was approximately 3 000 m2. The test results of the high-density resistance method were similar to those of the drilling exploration method. We conclude that the high-density resistance method has considerable application value for empirical cases and is recommended to be used simultaneously with the drilling method. Combined application of the highdensity resistivity and drilling methods will reduce costs, improve the accuracy of judicial appraisal, and provide new ideas for empirical research on agricultural environmental damage. |
